Abstract (en)
[origin: US11316503B2] A phase and/or amplitude modulation device includes a TORP signal generator and, during a phase modulation or a phase and amplitude modulation, a generator of a phase-modulated periodic signal of frequency FPRP applied to a control input of the power supply circuit of the TORP signal generator. The device may also include, during an amplitude modulation or a phase and amplitude modulation, 2P TORP generators, a thermometric code generator on 2P bits coding an amplitude modulation, a TORP generator control circuit, applying or not, to the control input of the TORP generator power supply, the periodic signal of frequency FPRP depending on the bits of the thermometric code signal, and a processing circuit coupled to the outputs of the TORP generators, and configured to produce a linear combination of signals outputted by the TORP generators.
